Importing amd.js/umd/es6 modules would be preferred, but you could also include your .js files using the preamble option.

I think I used foreign-libs at the end. I might have had preamble there at one point, but that iteration did not work. Using Figwheel + Devcards build in Leininged seems to swallow compile information, or at least I couldn't see any error messages unless I broke the build very badly...
